Downhole tubular system, downhole tubular and method of forming a control line passageway at a tubular

Abstract

A downhole tubular system including a tubular defining a wall having an inner radial surface and an outer radial surface, the outer radial surface having a circumferential channel formed therein extending 360 degrees defining a punch portion, the inner radial surface defining an inner bore; a sleeve attachable around the tubular; and at least a portion of a control fluid chamber passageway defined between the sleeve and the outer radial surface, the wall occluding fluidic communication between the control line passageway and the inner bore until the punch portion has been punctured.

What is claimed is: 
     
       1. A downhole tubular system comprising:
 a tubular defining a wall having an inner radial surface and an outer radial surface, the outer radial surface having a circumferential channel formed therein extending 360 degrees defining a punch portion, the inner radial surface defining an inner bore; 
 a sleeve attachable around the tubular; and 
 at least a portion of a control fluid chamber passageway defined between the sleeve and the outer radial surface, the wall occluding fluidic communication between the control line passageway and the inner bore until the punch portion has been punctured. 
 
     
     
       2. The downhole tubular system of  claim 1 , wherein the sleeve provides at least one of tensile, compressive, and bending load support to the tubular. 
     
     
       3. The downhole tubular system of  claim 2 , further comprising a collar, attachable to the sleeve and a lock ring attachable to the tubular. 
     
     
       4. The downhole tubular system of  claim 1 , wherein the sleeve is threadably engaged with the tubular at at least one location. 
     
     
       5. The downhole tubular system of  claim 1 , further comprising seals sealingly engageable with both the tubular and the sleeve offset to both longitudinal sides of the punch portion. 
     
     
       6. The downhole tubular system of  claim 1 , wherein the punch portion has a consistent radial thickness around the full 360 degrees of the tubular. 
     
     
       7. The downhole tubular system of  claim 1 , wherein an opening punched anywhere through the punch portion creates fluidic communication between the inner bore and the control line passageway through the opening. 
     
     
       8. A tubular for downhole use comprising a wall defining an inner radial surface and an outer radial surface, the outer radial surface having a circumferential channel formed therein extending 360 degrees defining a punch portion, the inner radial surface defining an inner bore, and the outer radial surface being configured to connect with a sleeve to define a control line passageway between the outer surface and the sleeve, the punch portion occluding fluidic communication between the inner bore and the control line passageway until punctured. 
     
     
       9. The tubular of  claim 8 , wherein the punch portion is configured to allow fluidic communication between the inner bore and the control line passageway after an opening is punched through the punch portion. 
     
     
       10. The tubular of  claim 8 , wherein the punch portion has a consistent radial thickness around the full 360 degrees of the tubular. 
     
     
       11. A method of forming a control line passageway at a tubular for downhole use comprising:
 providing a tubular with a wall having an inner radial surface and an outer radial surface, the inner radial surface defining an inner bore, the outer radial surface having a channel formed 360 degrees around the tubular defining a punch portion; and 
 providing a sleeve configured to be attached to the tubular such that a control line passageway is defined between the sleeve and the outer radial surface, the control line passageway being occluded from fluidic communication with the inner bore until an opening is punched through the punch portion. 
 
     
     
       12. The method of  claim 11 , further comprising:
 providing a collar for attaching between the tubular and the sleeve; and 
 providing a lock ring for attaching between the tubular and the sleeve, the tubular, sleeve, collar and lock ring being configured such that when assembled together the sleeve provides structural support to the tubular. 
 
     
     
       13. The method of  claim 11 , further comprising sealingly engaging the sleeve to the tubular at two longitudinal offsets from the punch portion.
